Emergency Department

You never know when you'll have a medical emergency, but you always know that you can go to Henry Mayo Newhall Hospital.

Our average wait time is based on how busy our Emergency Department has been in the last hour and is intended to give you a general idea of how busy our Emergency Department is. We define wait time as the time it takes for a patient to see a physician. Conditions in our Emergency Department change rapidly. Based on the severity of your condition and that of others in the Emergency Department, your wait time may be longer or shorter than the wait time you see posted online.

Our Emergency Department is open 24 hours a day, seven days a week with access to state-of-the-art medical equipment. Designated as a Level II Trauma Center, Henry Mayo is proud to have expanded our ED facility with features including a trauma room, cardiac-monitored beds, a spacious nursing station, plus more privacy for our patients. Our ED staff has also received special training to treat pediatric patients. In addition, we are certified by and adhere to standards set by The American Heart Association for emergency cardiac care. And most of our nurses are certified in Mobile Intensive Care, trained to communicate via radio with paramedics.

Upon arrival to our Emergency Department, every patient is evaluated by one of our trained Triage Registered Nurses. A triage assessment includes chief complaint, vital signs, allergies, medications taken and past medical history. Based on this assessment, patients are assigned a priority level of services.

When is a visit to the Emergency Department warranted? According to the American College of Physicians, warnings signs include (but are not limited to):

Sudden pain

Sudden dizziness

Headache or a change in vision

Weakness or fainting
